Definitions

  • the present invention relates to an insole.
  • pneumatic insoles are often used for a better comfort in walking due to the better absorption of the ground unevenness by the insole.
  • insole contains a fluid, such as for example, pressurized air, and are therefore better fitting the different anatomy of the user.
  • a normal inconvenience of these types of insoles is that the air tends to expand in a non uniform way inside the insole, for example moving into regions of the insole opposite to the regions where the foot exerts a pressure, and causing considerable annoyance.
  • insoles have been provided with several dividing baffles in an attempt to better distribute the air inside the insole.
  • the air pressure forms protrusions between the baffles, where the material forming the insole resiliently yields.
  • the aim of the present invention is to eliminate the above described inconveniences of the prior art, providing an insole, with a high technical performance, which, beside providing the shoe with a high comfort, allows to vary the flexibility of the shoe according to the user's needs.
  • an important object of the invention is to provide a high technology insole adapted to perfectly distribute the fluid inside the insole and at the same time leaving the surface in contact with the foot substantially unaffected.
  • a further object of the invention is to provide an insole wherein the thickness can be varied in some sections, according to the user's needs.
  • Still a further object of the invention is to provide an insole that can be either removable or permanent in any type of shoe, and that in any case remains unaffected by the wear of the sole and/or upper.
  • an insole characterized in that it comprises at least a first member and a second member, in a material impermeable to a fluid, said members being tightly associated at their perimetric surfaces in order to form at least one cavity between them, said cavity having distributing means for a uniform and capillary distribution of said fluid in said cavity, said distributing means occupying the entire volume of said cavity.
  • Fig. 1 is a top plan view of the insole according to the invention.
  • Fig. 2 is a perspective exploded section view, according to the line II-II of figure 1 , according to the invention
  • Fig. 3 is a schematic exploded view of the insole according to the invention.
  • the insole according to the invention comprises at least a first member and a second member, made of a material impermeable to a fluid, for example air, and respectively designated by numerals 2 and 3.
  • the members 2 and 3 are mutually tightly associated along their perimetric surface 4.
  • the first and second members 2, 3 form at least one cavity 20 between them.
  • Distribution means 5 for a uniform and capillary distribution of the air inside the cavity 20, are arranged inside the same cavity 20.
  • the distribution means 5 is defined by an open cell material; a section of this material is shown in Fig. 2.
  • the open cell material occupying the entire cavity volume, has the same shape of the cavity and its upper and lower faces, respectively 6 and 7, are associated with the first and second member 2 and 3, respectively.
  • the open cell material 5 may have one or more regions 10 having different density and/or different thickness.
  • the region 11 has a different density and/or thickness with respect of both the open cell material 5 and of the two regions 10 which both have the same density and/or thickness.
  • the open cell material may be a fabric, expanded plastics, or any other type of adapted material, and it is associated with the first and second impermeable members by known systems, such as gluing, welding, vulcanization, etc.
  • the insole is provided so that the air inside the cavity has a selected pressure according to the type of shoe.
  • the insole has instead a valve 12 for charging and discharging air inside the cavity.
  • valve 12 is arranged in a region of the cavity at the arch of the user's foot.
  • a conduit 13 is connected to the valve 12 and has a free end substantially in contact with the open cell material 5.
  • the regions 10 and 11 having different thickness and density, have their edges perfectly matching the edges of the remaining part of the material 5, and since the conduit 13 is in contact with the open cell material, the fluid is prevented from forming pockets and therefore from forming annoying protrusions on the surface of the insole.
  • the insole also has a supplemental member 14 for covering the first and/or second impermeable members 2 and 3, ensuring a perfect comfort and transpiration of the foot.
  • the insole thus conceived may be removably arranged as an anatomical arch support in any type of shoe, or it can be provided, during assembly of the shoe, as a fixed and permanent part.
  • the insole according to the invention will not suffer from wear of the sole or upper and will be easily replaced if damaged.
  • variable quantity of fluid is modified for varying the flexibility of the insole, according to the user's needs.
  • variable fluid pressure inside the cavity defines a pneumatic suspension which can be modified according to the user's weight or to his/her requirements.
  • the insole will always have a mechanical suspension of the user's foot, formed by the open cell material inside the insole.
  • the open cell material being tightly associated with the surfaces of the first and second members 2 and 3, also allows a perfect distribution of the fluid inside the cavity.
  • planarity of the insole can be modified by varying the density and/or the thickness of the open cell material and by varying the pressure of the fluid inside the cavity.
  • the materials employed, as well as the dimensions, may be any according to the specific needs and the state of the art.

Abstract

Cette semelle intérieure comprend au moins des premier et second éléments, composés d'un matériau imperméable aux fluides et étroitement réunis l'un à l'autre au niveau de leur surface périphérique afin de définir une cavité pourvue de moyens destinés à la distribution capillaire uniforme du fluide dans la cavité. Le moyen de distribution occupe tout le volume de la cavité.
